--- Comment #2 from mikulas at artax dot karlin.mff.cuni.cz ---
I can reproduce it with
gcc-4.8.4 on Ubuntu 14.04 on native armhf (it doesn't reproduce with gcc-4.9 on
the same machine)
arm-linux-gnueabi-gcc-6 cross-compiler on Debian Stretch
arm-linux-gnueabi-gcc-7 cross-compiler on Debian Sid

If you have x86-64 Debian Stretch or Sid, install the package
"gcc-arm-linux-gnueabi" to reproduce this bug.
